Application filed August 9,

To allwhom it may concern:

Be it known that I, DANIEL W. K ITH, a citizen of the United States, residing at Keithville, in the parish of Gaddo and tfitate of Louisiana, have invented certain new and useful Improvementsv in'Pumps, of which the following is a specification.

This invention relates to improvements in pumps especially adapted for use in con nection with wells and cisterns.

An important object of'this invention is to provide a well pump having a plurality of pumping cylinders which may be alternately brought into communication with the discharge pipe or conduit by means of a single pivoted valve. I

A further object of this invention is to provide a well pump having means whereby the water within the discharge pipe may be returned to the well at the completion of the pumping operation so that the water will be kept cool.

A further object of the invention is to provide a pump of the'class described which is of highly simplified construction, reliable in use and cheap to install.

Other Objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is an elevation of the improved r p, I

Figure 2 is a detail sectional view through the same, the view illustrating the valve arrangement, g I f Figure 3 is aside elevation of a slightly modified form of invention,

Figure 4 is a detail sectional view of the pump having a slightly modified valve arrangement.

In the drawing wherein for the purpose offillust ration is shown a preferred embodiment of the invention, the numeral 10 generally designates the improved pump comprising cylinders 12 and 14 arranged in spaced parallel relation and preferably embedded 1n the ground so that the openings 16 and 18 respectively in the lower ends of the same are disposed below the water level, whereby the water may be drawn into the cylinders. I

Pistons 20 and 22 are slidably mounted within the cylinders 12 and 14 respectively As the water through the channel piston 20, the piston Specification of Letters Patent. Fatntad A111. 18, 1922- 1920. Serial No. 402,114.

and have piston rods 24 connected to a crank shaft 26 by means of links 28. In the form of the invention illustrated in Figure 1, the

.crank shaft 26 is rotatably supported upon the bearings 30 carried by the standards 31 ofa platform designated by the numeral 32. The-crank shaft is provided with an operatingcrank 34 which is adapted to be manually rotated. A wheel 33 may be mounted upon one end of the crank shaft so that the crank shaft may be rotated by a suitable source of motive power. During the upward movement of the piston 20, a quantity of water is drawn from the well or cistern through the opening 16 into the cylinder 12. A flap valve 38 is horizontally pivoted. in the lower portionof the chamber as indicated at 39 and during a subsequent downward movement of the piston closes the opening 16 and thereby prevents the return of the water to the well or cistern. During the downward movement of the piston, the water is forced through a lateral through a passage 41 in a valve casing 42. is forced through the passage 41 in the valve casing 42, the same enters a V-shaped chamber 44 within which a V- shaped valve 45 is horizontally pivoted as indicated at 46. The passage of water 41 of course moves the valve 45 to the left and thereby allows the water to pass through the V-shaped chamber 44 into a discharge pipe or conduit 47.

During the downward movement of the ing of an upward movement thereby drawing water from the well to the cylinder 14 V r through the opening 18. As the wateris drawn into the cylinder 14, a horizontally pivoted or hinged flap valve 48 is elevated so as to uncover the opening'18. 'On the subsequent downward 22 the water is forced downwardly and the flap valve 48 closes the Opening 18 so that the water is directed through an opening 50 in the side wall of the cylinder 14 and then through a passage 51 in the valve casing 42. The passage of the water through the passage 51 moves the horizontally pivoted valve 45 to the right and thereby establishes communication between the passage 51 and the chamber 44. The passages 41 and 51 are inclined upwardly in the direction of the discharge conduit 47 so that the water may freely enter the conduit upon leaving the movement of the piston 22 is of course partak casing 42. This movement of the horizontally pivoted valve closes the passage 41 so that as the piston moves upwardly in the cylinder 12, the water will not be allowed to flew back throug-hthe passage 41.

The pipe 47 may extend to a suitable point of discharge or may have a spout 5 1- at a point above the ground.

As illustrated in Figure 1, the discharge pipe 47 is provided with a drain pipe 55 which extends back into the cistern or well so that when the pumping operation is completed the water within the pipe 417 -will return to the well and In the form ofthe invention illustrated in Figure 3, the upper ends of the links 28 are pivoted to a lever 60 having one end portion formed with a handle 61 adapted to be moved vertically so as to impart a corresponding movement to the piston rods 2 1. In this form of the invention, .the discharge conduit 47 has its upper end formed with apertured ears 62 between which the intermediate portion of the lever 61 is horizontally pivoted by means of a pin 6 vThe form of operating means illustrated in Figure 3, allows the operator to draw a constant and uniform stream of water through the discharge conduit 17. The conduit 17 may, in both forms of the invention, be provided with a bracket 65 having vertically arranged sleeves 66 which slidably receive and guide the vertically movable piston rods 241.

WVith reference to Figure 41, it willbe observed that flap valves 38 and/18 may be dis-V placed by spherical valves 68 adapted to seat on the upper walls of the openings 16 and 18 so that the same will beelevated upon the passage of water through the openings. The spherical valves may be provided with stems 70 having their lower portions provided with retaining disks 71 which serve to limit the upward movement of the spherical valves. 7 V

The lower portions of the cylinders 12 and 14: may be supported in spaced relation 'to thebottoniof the well by means of a plurality of vertically arranged standards 7 1' mountedupon a fiatbase 75. p

With reference to thet'oregoing description taken in connection with the accom panying drawings, it will be observed that a pump constructed inaccordance with this invention may be conveniently operated with V a minimum of efiort on the part of the thereby be kept cool.
